Another object of the present invention is to provide a break display lamp which is disposed in a switch device to be discontinued while overloading.
Another object of the present invention is to provide a dark display lamp which is disposed in a plug to be operated while overloading.
Another object of the present invention is to provide a break display lamp which is disposed in a plug to be discontinued while overloading.
Accordingly, a switch device comprises a conventional fuseless breaker device, a first conductive blade, a second conductive blade, a fixed plate, and a movable plate connected to the fixed plate. The breaker device comprises a metal bar having two expansion coefficients, an insulator plate disposed in the switch device, a safety button disposed on a top end of the insulator plate, and a coiled spring disposed on an upper portion of the insulator plate. The metal bar contacts the first conductive blade. A pressing button is disposed on the switch device. The pressing button has a first portion and a second portion. A lamp assembly is disposed in the pressing button. The lamp assembly has a break display lamp and a dark display lamp. The break display lamp is disposed in the first portion of the pressing button. The dark display lamp is disposed in the second portion of the pressing button. A pressing pin is disposed in the switch device. A compression spring is disposed in the switch device. A first pin of the break display lamp is connected to the pressing pin and the compression spring. A second pin of the break display lamp is connected to a resistor.
